Gigapascals to Megapascals converter

To convert gigapascals to megapascals, enter the value in the first field. The result in megapascals is calculated automatically using the exact conversion factor.

1 GPa = 1000 MPa
1 MPa = 0.001 GPa

Formula: MPa = GPa × 1000
GPa = MPa × 0.001

Definitions: 1 GPa = 1000000000 Pa; 1 MPa = 1000000 Pa

The gigapascal (GPa) is one billion pascals. It is used for very high stresses and for stiffness (Young's modulus), where steel is about 200 GPa, and for pressures deep inside the Earth.

The megapascal (MPa) is one million pascals, or one newton per square millimeter. It is the standard unit for material strength, hydraulic pressure and high-pressure equipment, and for stress in steel and concrete.
